(轉)Memcached 之 .NET（C#）執行個體分析

標籤：style   class   blog   c   code   java   

一：Memcached的安裝

step1. 下載memcache(http://jehiah.cz/projects/memcached-win32)的windows穩定版（這裡我下載了memcached 1.2.1 for Win32 binaries (Dec 23, 2006) 這個版本），解壓放某個盤下面，比如在c:\memcached
step2. 在終端（也即cmd命令介面）下輸入 ‘c:\memcached\memcached.exe -d install’ 安裝
step3. 再輸入： ‘c:\memcached\memcached.exe -d start’ 啟動。

          PS: 以後memcached將作為windows的一個服務每次開機時自動啟動。這樣伺服器端已經安裝完畢了。

 

二： .NET memcached client library
       下載檔案：https://sourceforge.net/projects/memcacheddotnet/ 

       將Commons.dll，ICSharpCode.SharpZipLib.dll，log4net.dll，Memcached.ClientLibrary.dll 等放到bin目錄

       引用Memcached.ClientLibrary.dll
